WEFT-REPLENISI-IING LOOM.

To all whom it may concern:

Be it known that I, EPPA H. RYoN, a citizen of the United States,residing at Waltham, in the county of MiddleseX and State ofMassachusetts, have invented certain new and useful Improvements inWeft-Replenishing Looms, of which the following is a specification.

My invention relates to weft replenishing looms, and more particularlyto that class of weft replenishing looms shown and described in U. S.Letters Patent, No. 933,492, which looms have a stationary magazine witha plurality of guide-ways or compartments for bobbins or fillingcarriers, and in which, when the lowest bobbin in a compartment isreleased, said bobbin drops down by gravity to the discharging end ofthe magazine, to be engaged by the transferrer arm to be transferredinto the active shuttle.

In looms of the class referred to, which have a stationary magazine withfour or more guide-ways or compartments for bobbins or filling carriers,and in which the dis tance for some of the bobbins to drop to thedischarging end of the magazine is considerable, it may happen that abobbin is misplaced and will not fall into its proper po sition at thedischarging end of the magazine.

The object of my invent-ion is to provide mechanism for positivelypositioning a bobbin after it has been released from its compartment,and preparatory to its being transferred into the active shuttle.

My mechanism, as shown and described herein, for positioning a bobbin,consists of two blades, one at each side of the magap in my pendingapplication, Serial No.

Specification ,of Letters Patent.

Application filed December 1, 1910.

Serial No. 595,016.

581,387, suflicient to enable those skilled in the art to understand theconstruction and operation of the same.

Referring to the drawings :Figure 1 is an inner end view of a magazine,and a bobbin holding and releasing mechanism, with my improvementscombined therewith, looking in the direction of arrow a, Fig. 2. Fig. 2is a front view of a detached portion of the stationary magazine, shownin Fig. 1, looking in the direction of arrow 7), same figure. Fig. 3 isa section, on line 3, 3, Fig. 2, looking in the direction of arrow 0,same figure; the lowest bobbin at the left is released from itscompartment and dropped into its support. Fig. 4: is a front view of themagazine, looking in the direction of arrow d, Fig. 3, with a verticallymoving bar raised to release a bobbin from its compart-ment. Fig. 5corresponds to Fig. 3, but shows the bobbin at the left dropped to thedischarging end, and the positioning device in its opposite position.Fig. 6 is a section, on line 6, 6, Fig. 5, looking in the direction ofarrow 6, same figure, and, Fig. 7 shows a bobbin released from itscompartment and held by its support.

In the accompanying drawings, 1 is the breast beam, 2 a stationary standmounted thereon, which has secured thereto the inner end 3 of themagazine, which in this instance has six vertically extending guide-waysor compartments 3 for the heads 4 of the bobbins 4. The bobbins 4c arearranged in siX sets or series, one set for each compartment, and dropdown by gravity to the lower discharging end 3 of the magazine. Eachguide-way or compartment 3 is provided at its lower end with mechanismsfor supporting the set of bobbins therein, and also for releasing eachbobbin in each set, preparatory to its passage to the discharging end 3of the magazine, to be transferred into the active shuttle. In thisinstance the holding and releasing mechanism consists of two slidingblades or bars 5 and 6, which are suitably guided at each end, andprovided with project-ions 5 and 6 on one side thereof, for the head andthe tip of the bobbins to rest upon, and to be released when a slidingmotion is communicated to the blades 5 and 6, and the projections 5 and6 are to be moved out of the path of the bobbins, or away from the headand tip of the bobbin.

Arranged on the inner side of the inner end plate 3 of the magazine are.six vertically moving bars 7 one for each compartment 3. The bars 7 areloosely supported in guides or bearings 3, and have an up and downmovement. The bars are provided at their upper ends with weighted hooks8, which are adapted, on their downward movement, to engage and rock alever 9, which has its hub 9 secured on a rock shaft. 10. The outer endof the shaft 10 has secured thereon the hub 11 of an arm 11. A stud 12of the arm 11 enters a hole in a block 13, and is adapted to looselyextend in an elongated opening in a lever 14, which has its hub 14loosely mounted on a stud 15. A helically coiled expansion spring 16acts to hold and lock the levers l4 and 11 in their upper and lowerposition. A second arm 14 of the lever 14 is adapted, through connector15, and intermediate connections to the dagger on the transfer arm, notshown, to raise said dagger into the path of the bunter on the lay, totransfer the bobbin being released into the active shuttle, in the usualway.

The bearings 3 on the magazine have loosely mounted therein alongitudinally moving rod 16. A sliding motion is communicated to therod 16, through intermediate connections, to the drop shuttle boxes, ora pattern surface on the opposite side of the loom, not shown.

The raising and lowering of the shuttle boxes, or the movement of thepattern chain, will impart a reciprocating movement to the rod 16, tocause it to move longitudinally into six different positions, accordingto the positions of the drop shuttle boxes, or the pattern indicators;

Extending upwardly from the weft replenishing operating mechanism on theloom, not shown, is a rod 17, which has its upper end pivotallyconnected to a pin 18 on a lever 19, which has its hub loosely mountedon the rod 16, and is prevented from having a longitudinal movementthereon by the two lugs or bearings 3 The lever 19 is provided with lugs19, t o loosely receive the spring actuated bolt 20, which, through theaction of the helically coiled expansion spring 21 at the horizontalposition of the lever 19, shown in Fig. 2, bears against the stand 2,and prevents said lever from moving downwardly, unless through theaction of the weft replenishing mechanism, not shown.

The longitudinally moving rod 16 has secured thereon, to be movedtherewith, the hubs 22 of the operating lever 22. A side extension 22",which extends looselyinto a notch or recess in the lever 19, will,through the up and down movement of said lever, communicate a rockingmotion to the lever 22 and through fingers on said lever, which engageextensions 7 on the vertically moving bar 7, move up or down theselected bar to release a bobbin. The lower ends of the bar 7 are forkedor yoke-shaped at 7", as shown, and provided with a curved slot 7', seeFig. 2, into which extends the studs 5 and 6", respectively, of each ofthe sliding blades 5 and 6.

The up and down movement of the vertically moving bar 7 causes a slidingmotion of the blades 5 and 6, in a direction away from each other, torelease and drop a bobbin from its compartment.

All of the above mentioned parts are of the construction shown anddescribed in U. S. Letters Patent, No. 933,492, and in my pendingapplication, Serial No. 581,387, above referred to.

I will now describe my improvements, which as above stated relate to thepositioning device or mechanism for a bobbin being released from itscompartment in the magazine, preparatory to being transferred into theactive shuttle. The lever 9 is provided in this instance with two lugsor ears 9, which are pivotally connected to the lower ends of the twoupwardly extending rods 23 and 24. The upper boss 23, on the rod 23, ispivotally connected to a stud 25 on an arm or lever 26, and the boss 24on the connector rod 24, is pivotally connected to a stud 27, on an armor lever 28. The arms 26 and 28 have their hubs loosely pivoted on astud 29 on a projection 3 on the magazine. The arm 26 has pivotallyconnected to its end the upper end of a downwardly extending wire or rod30. The lower end of said rod 30 has pivotally connected thereto theupper link of a flexible chain 31. The chain 31 extends downwardly andinto a guide 32, which is hollow throughout its central portion. Thechain guide 32 is suitably secured to the magazine, and leads inwardlytoward the discharging end 3 of the magazine. The lowest link on thechain 31 has outwardly extending therefrom a rod or wire 33, which hasthereon a blade 34, as

shown in Figs. 4 and 6.

The lever or arm 28 has pivotally connected thereto the upper end of adownwardly extending rod 35; the lower end of the rod 35 has pivotallyconnected thereto the upper link of a flexible chain 36, which in thisinstance extends downwardly and into a chain guide 37, which is hollowthroughout its central portion and extends at its lower part toward thedischarging end 3" of the magazine. The lower link of the chain 36 has arod or wire 38 extending out therefrom which is provided with a blade39, similar to the blade 34, of the other chain 31. A helically coiledcontraction spring 40 is attached to the extension 23 and 24 on theconnections 23 and 24, and act to yieldingly hold the levers 26 and 28in their raised, and lowered position.

From the above description in connection with the drawings, theoperation of my improvements will be readily understood by those skilledin the art, and briefly is as follows :-When, through the operation ofthe weft replenishing mechanism, a vertically moving bar 7 is movedupwardly, as shown in Fig. 7, a bobbin 4 is released from itscompartment to drop onto the lower part of the bobbin supports 5 and 6,as shown at the left in Fig. 3, and on the downward movement of the bar7, the weighted book 8 engages the lever 9, and moves said lever fromthe position shown in Fig. 4 to the position shown in Fig. 6. The bobbin4 drops from its support to the lower part of the magazine, and as thearms 26 and 28 are moved downwardly, through connections to the lever 9,the chains 31 and 36, and the blades 34 and 39 are operated, to followthe passage of the released bobbin, to engage and positively move it tothe discharging end 3 of the magazine, and properly position it, asshown in Fig. 5.

It will be understood that the details of construction of myimprovements may be varied if desired.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. In a magazine of the class described, a plurality of compartments forstacks of superposed bobbins, supports for the lowest bobbin in eachcompartment, means to operate said supports to release a bobbin from acompartment, guides or projections on which said bobbin rest-s whenreleased from the magazine, movable blades or pushers, and means toautomatically operate said blades or pushers to place a released bobbinin position to be transferred into the shuttle.

2. In a magazine of the class described, having a plurality of stacks ofbobbins,

means to support said bobbins, guides or projections arranged below saidsupports, means to operate said supports to release the lowest bobbin inany compartment, and means to positively push said bobbin to a positionto be transferred into the shuttle.

3. In a magazine of the class described, a plurality of compartments forsuperposed bobbins, supports for said bobbins, slides operativelyconnected to said supports, a pair of pushers to force a bobbin, whenreleased by said supports, to a position to be transferred into theshuttle, and connections between said pushers and said slides.

4. In a magazine of the class described, a plurality of compartments forsuperposed bobbins, supports for said bobbins, slides operativelyconnected to said supports, a pair of pushers to force a bobbin, whenreleased by said supports, to a position to be transferred into theshuttle, and flexible connections between said pushers and said slides.

5. In a magazine of the class described, compartments for a plurality ofsuperposed bobbins, supports for the bobbins in each compartment, meansto operate said supports to allow a bobbin to drop from the compartmentto a projection or guide, and said projection or guide, and devicesautomatically operated in opposite directions to positively push abobbin to a position to be transferred into the shuttle.
